SSC JE Mechanical Syllabus 2026: Paper I and Paper II Topics

The SSC JE Mechanical syllabus covers two computer-based papers. Paper I tests General Intelligence and Reasoning, General Awareness and General Engineering Part C (Mechanical). Paper II tests only Part C, in more depth. The Staff Selection Commission sets the standard of the engineering questions at roughly the level of a diploma in engineering, so the syllabus suits both diploma and degree holders.

This page sets out the 2026 syllabus subject by subject, as listed in the Junior Engineer Examination 2026 notice. It also shows which topics deserve most of your time, how the two papers overlap, and a phased plan to finish the syllabus before the exam. Because Paper I is now qualifying and Paper II alone decides merit, how you divide your time between the two has changed this cycle.

SSC JE Mechanical Syllabus 2026 at a Glance

Both papers are objective and set in Hindi and English. Paper I deducts 0.25 marks per wrong answer and Paper II deducts 1 mark.

Key Changes to Know

• Paper I is qualifying: From the 2026 cycle, Paper I marks only decide who is shortlisted for Paper II. They are not added to the final score.

• Paper II carries the full merit: The 300-mark Part C paper alone decides your rank, so the mechanical syllabus now matters more than ever.

• Paper II is objective, not descriptive: Some older pages still describe a conventional or descriptive Paper II. The current Paper II is a computer-based multiple-choice test.

• Same headings in both papers: The notice uses the same 11 mechanical subject headings for both papers and lists detailed sub-topics for Paper II.

Paper I Syllabus: General Intelligence and Reasoning

This section includes verbal and non-verbal questions. SSC describes it as testing your ability to deal with abstract ideas, symbols and their relationships, along with arithmetical reasoning and analytical function.

Paper I Syllabus: General Awareness

General Awareness tests your knowledge of current events and everyday observations, including scientific aspects that an educated person is expected to know. The notice also mentions questions on India and its neighbouring countries. No special study of any one discipline is needed.

Engineering students often find general science easy because it overlaps with basic physics and materials. Use that advantage, and spend the remaining time on static GK and current affairs.

SSC JE Mechanical Engineering Syllabus (Part C)

This is the core of the exam. Paper I includes 100 questions from these subjects, and Paper II asks 100 deeper questions from the same list. The sub-topics below follow the 2026 notice.

Engineering Mechanics and Strength of Materials

• Engineering Mechanics: Free body diagrams, conditions of equilibrium, friction, centroid and centre of gravity.

• Strength of Materials: Simple stress and strain, elastic constants, shear force and bending moment diagrams, bending and shear stresses in beams, deflection of beams, torsion of shafts, thin cylinders.

Theory of Machines and Machine Design

• Theory of Machines: Cams, belt and gear drives, gear trains, flywheels, governors, balancing of masses, vibrations, brakes, dynamometers, clutches and bearings.

• Machine Design: Loads and stresses, creep and fatigue, theories of failure, riveted and welded joints, keys, shafts, couplings, springs and fasteners.

Materials Science and Engineering

• Structure and phases: Crystal structures, the iron-carbon equilibrium diagram, phase transformations.

• Heat treatment and alloys: Annealing, normalising, hardening, tempering, types of cast iron and steel, non-ferrous alloys.

• Testing: Mechanical testing, non-destructive testing and corrosion.

Thermal Engineering

Fluid Mechanics and Hydraulic Machinery

• Fluid basics: Properties of fluids, pressure and its measurement, fluid statics.

• Fluid flow: Continuity equation, Bernoulli's equation and its applications, flow through pipes and losses.

• Machines: Impact of jets, hydraulic turbines (Pelton, Francis, Kaplan) and pumps (centrifugal and reciprocating).

Industrial Engineering

• Planning and layout: Plant layout, production planning and control.

• Work and quality: Work study (method study and time study), quality control and inventory control.

Manufacturing Engineering

• Casting: Patterns, moulding and casting processes and defects.

• Forming and joining: Metal forming processes, welding processes and press working.

• Machining: Lathe, drilling, milling, shaping and grinding operations, tool life and cutting parameters.

Metrology and Measurement

• Concepts: Accuracy, precision, calibration and errors.

• Instruments: Linear and angular measurement, comparators, surface finish measurement, coordinate measuring machines (CMM).

• Fits: Limits, fits and tolerances.

Advanced Manufacturing Processes

• Production aids: Jigs and fixtures.

• Automation: CNC machines, PLC, CAD and CAM, industrial robots and flexible manufacturing systems (FMS).

• Non-traditional machining: Processes such as EDM, ECM, USM, LBM and abrasive jet machining.

High-Weight Topics in SSC JE Mechanical

SSC does not publish subject-wise weightage. The guide below is based on how questions have been spread in previous years' papers, so use it to prioritise, not as an official split.

Do not drop the lower-priority subjects. In Paper II every question carries 3 marks, so even a small subject can move your rank.

Overlap Between Paper I and Paper II

The gap between Paper I and Paper II is usually short. Plan to finish the full mechanical syllabus before Paper I, and use the time after it purely for Paper II revision and mocks.

How Questions Differ Between the Two Papers

The subject list is the same, but the way SSC tests it changes between the papers. Knowing this helps you decide how deep to go in each topic.

These examples show the usual trend in past papers, not a fixed rule. Both papers can include theory and numericals, but Paper II leans more towards applied and calculation-based questions. Because each Paper II question carries 3 marks and a wrong answer costs 1, careful working matters more than speed there.

Study Sources for the Mechanical Syllabus

• Official notice: The syllabus annexure in the SSC JE notice is the final word on what is in scope. Keep a printed copy and tick off sub-topics as you finish them.

• Diploma and degree textbooks: Since the standard is roughly diploma level, your own course textbooks for thermal engineering, fluid mechanics, strength of materials and manufacturing are a sound base.

• Previous year papers: They show which sub-topics SSC returns to and the level of numericals. Solve at least the last few years' papers subject by subject.

• School-level science for GA: For the general science part of General Awareness, basic physics, chemistry and biology from school textbooks is usually enough.

• A daily news source: For current affairs, read one reliable newspaper or government news source and keep monthly notes.

Avoid collecting too many books for one subject. One good textbook, one question bank and your own notes are easier to revise than five half-read sources.

How to Cover the SSC JE Mechanical Syllabus

1. Weeks 1 to 6, build the core: Cover thermal engineering, fluid mechanics, strength of materials and theory of machines. Make a short formula sheet for each subject as you go.

2. Weeks 3 onwards, add Paper I sections: Add 30 to 40 minutes of reasoning and 20 to 30 minutes of current affairs each day, with monthly GK notes.

3. Weeks 7 to 10, complete Part C: Finish manufacturing, materials science, machine design, industrial engineering, metrology and advanced manufacturing. Start topic-wise tests after each subject.

4. Weeks 11 to 12, Paper I mocks: Take full-length Paper I mocks and keep your reasoning and GK sections within time.

5. After Paper I, Paper II focus: Revise formulas, solve numericals and take Paper II-style mocks where a wrong answer costs 1 mark. Revise from your error log after every test.

Previous year papers show how SSC frames questions from each heading, especially in thermal and fluid mechanics. Testkart also lets you review previous year questions with section-wise analysis, so you can see which sub-topics keep repeating.
